Her joints are doing better
“Honestly, I wasn’t sure if a collagen supplement would make a big difference, but it really has. My dog eats it up with no problem, and her coat looks way shinier and softer. She’s barely shedding now, and I can tell her joints are doing better when we go on walks. Super happy with this so far!”
Going to buy again
